Answer:

coordinates of D are ( -8, 5)

Step-by-step explanation:

- the formula of the coordinates of the midpoint is (x1+x2)/2  & (y1+y2)/2

- first we find midpoint C by using coordinates of points A and B

C => (4 - 12)/2 & (8 + 4)/2

calculate, coordinates of C are ( -4, 6 )

- now find midpoint D by using the coordinates of B and C

D => ( -12 - 4 )/2 & (4 +6)/2

calculate and the coordinates of D are ( -8, 5 )

What is the quadratic equation of least degree with zeros at 21 and -24
atroni [7]

Answer:

x^2 +3x -504

Step-by-step explanation:

Sort of do what you'd do to solve but in reverse.  You need 21 for a zero, so the binomial factor would be (x-21) since if you set that  = to zero you'd get 21.  Same for -24.  The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)

The graph for the equation y = x minus 4 is shown below. On a coordinate plane, a line goes through (0, negative 4) and (4, 0).
Nataly [62]

Answer:

The correct option is:

y - x = -4

Step-by-step explanation:

The graphed equation is:

y = x - 4

The equation which will have infinite number of solution should overlap the graphed equation at infinity points.

It is only possible when both the equations are exactly same.

Consider the line given:

y - x = -4

Rearrange the equation:

y = x - 4

Thus, it is the same as the first equation.

Verify for point (0,-4)

y - x = -4

-4 - 0 = -4

-4 = -4

Proved.

Verify for point (4,0)

y - x = -4

0 - 4 = -4

0 = -4+4

0 = 0

Proved

The voice onset time (vot) for the sound /da/ is 17 ms, and the vot for the sound /ta/ is 91 msec. When a computer produces a so
Archy [21]

The the /ta/ sound is the sound which listeners are likely to report hearing. The option B is correct option.

According to the statement

we have given that the The voice onset time (vot) for the sound /da/ is 17 ms, and the vot for the sound /ta/ is 91 msec. and we have to find the sound which listeners are likely to report hearing.

So, For this purpose, we know that the

Traffic announcement (TA) refers to the broadcasting of a specific type of traffic report on the Radio Data System. It is generally used by motorists, to assist with route planning, and for the avoidance of traffic congestion.

And according to this and the voice onset time is

The brief instant that elapses between the initial movement of the speech organs as one begins to articulate a voiced speech sound and the vibration of the vocal cord.

And according to this

the /ta/ sound is the sound which is the like by the listeners are likely to report hearing.

So, The the /ta/ sound is the sound which listeners are likely to report hearing. The option B is correct option.
